I've tried the search function but to no avail, I was thinking about upgrading my cd player to an aftermarket dash. Sony MEX-BT2500. It has bluetooth and an aux input for ipod, and all under 130 bucks. But Crutchfield wants to know if I got a bose system, because they said it requires a different wire harness. I searched the car and trunk, but didn't find anything that says bose on it. Could someone help me verify please. Thanks in advance.

 

Ooops I forgot to mention that my vehicle is a 2003 C230 Sedan.

 

The rear speakers should say "BOSE" right on the covers. Any Benz I have ever seen with a Bose system was this way.
